The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 9.94)  reporting on the development of a highly sensitive hydrogen sulfide (H2S) gas sensor exploiting the doubly resonant photoacoustic spectroscopy technique and using a near-infrared laser emitting at 1578.128 nm. We achieved a minimum detection limit of 10 part per billion Leggi di piùNew Publication on Photoacoustics Journal[…]

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 9.94)  reporting on a on a Near-IR quartz-enhanced photoacoustic sensor (QEPAS) for H2S leaks detection in matrixes containing up to 1 % of methane (CH4). An investigation of the influence of CH4 on H2S relaxation and photoacoustic generation was proposed in this Leggi di piùNew Publication on Photoacoustics Journal[…]
